Cold-Formed Steel Section with Bolted Connection to Estimate Total Cost and Maintenance

Abstract

A rise in the use of advisory services to monitor STA construction operations and aging, experienced, and turnover-prone STA construction workforces make it challenging for STAs to manage complex transportation networks. STAs receive construction-related human resources from Construction and Engineering Inspection (CEI) consultants in order to meet project requirements. However, no information has been gathered regarding the impact of CEIs on project schedules or costs. To fill in this information void, data from 305 completed highway construction projects in 16 STAs are being utilized. The study found that projects with CEI consultants had more full-time equivalent construction workers than projects with only agency workers. It had no effect on project costs when compared to programs that only used agency workers. CEI consultants While projects staffed by agencies had an average schedule overrun of 27.7%, CEI projects had an average expense overrun of 20.2%. The project was typically completed earlier than anticipated. There was a difference between the experiment's beginning and end times that was statistically significant.
